Unfortunately this latest post is being written with a little sadness, however it seems like we here in the US will be waiting at least another week for the now long-awaited Cupcake update. Yup, the previously posted OTA update schedule has officially been delayed.

According to the message posted on the T-Mobile Forums, the update has been delayed for “approximately a week” so they can “finalize the build” to “ensure optimal functionality and smooth delivery.” What this really means is that instead of having Android 1.5 on your G1 by the end of June, you are likely to see it sometime during the first week of June.

The update, which was posted on the T-Mobile Forums can be read below;

UPDATE:

G1 community,

We’d like to provide an update on the rollout of Android 1.5 for T-Mobile G1 customers.
We are working diligently to get Android 1.5 out as soon as possible, while aiming to ensure a consistent, positive experience for our customers. We’re finalizing the build this week to ensure optimal functionality and smooth delivery. Therefore, the rollout schedule has been reset by approximately a week, and we expect all G1 customers will have the update by early June.

Your device will notify you when the update is available. Thank you for your patience and understanding.

T-Mobile is delighted to announce the upcoming release of Android 1.5 with “Cupcake” coming soon to the T-Mobile G1! We plan to begin sending out the update starting the end of this week. As with previous software maintenance releases, the update will be randomly sent “over the air” to T-Mobile G1 customers. We expect everyone will have their update by the end of May.

"We’re finalizing the build this week to ensure optimal functionality…" Which begs the question, what have those who already have Cupcake been landed with? I know I shouldn't complain, having had 1.5 on my G1 for a couple of weeks now, but Cupcake has turned my lovely phone into a slow, forcequit-ridden disappointment. Is there any way to go back?
